I have just been reading through a few threads and have been compelled to join the forum just so that I can give Ted a pat on the back.
The more people we get using actual Science when discussing issues such as Alzheimer's (and Diabetes, Heart Disease, Cancer) the quicker the Western World will realise that Conventional Wisdom is not based on Science. Doctors are not taught more than a week's worth of Nutrition in 5 years of medical school - and most of that is still based on flawed pseudo-science from the 60s (ie. saturated fat is bad for you).
We evolved over millions of years, and we did it eating animals and plants. Not processed foods like pizza, pasta and that total hocus that is now called "bread". Dementia, Heart Disease, Cancer and Diabetes were all pretty much unheard of 100 or so years ago, yet now they are the "big 4" and have reached epedimic proportions across the Western World (depsite the advancements in medicine).
The 'healthy' low fat diet that is currently being pushed is (in my opinion) the main reason for the continued rise of these diseases.
The brain is made predominantly of fat and 20-25% of the body's total cholesterol is found in the brain. How can both of these things be so damaging to us? Cholesterol is what makes up the synapses within the brain. Is it too simplistic and logical to think that a low fat diet may just help in depriving the brain of it's most essential components?
A final thought. With both cholesterol and fat (especially saturated fat) being so bad for us (according to Conventional Wisdom) then why have the government or NHS not made moves to stop mothers breast feeding their babies? After all, mother's milk is made up of fat (50% saturated) and cholesterol? Hmm...
